Health-related quality of life in patients treated for hypertension: A review of the literature from 1990 to 2000

Background. The goals of antihypertensive therapy are to achieve and maintain blood pressure control by the least intrusive means possible to prevent future cardiovascular and renal events. To achieve these goals, pharmacologic agents must be chosen so as to minimize drug-related adverse events, increase patient adherence to treatment regimens, and minimize the negative impact on health-related quality of life (HRQL). Although the effects of antihypertensive therapy on HRQL have been extensively investigated, there is little synthesis of the research findings. Objective: This review was undertaken to provide a synthesis of the available data oil the impact of antihypertensive therapy on HRQL and to provide recommendations for future research. Methods: A MEDLINE literature search was conducted to identify English-language articles published from 1990 to 2000 that included random assignment to antihypertensive treatment and HRQL as an outcome. In addition, reference lists of published reviews and other trials were reviewed to identify other Studies of HRQL and antihypertensive therapy. Results: A total of 48 articles were included in the review. Results among studies were frequently inconsistent, which is likely due to the wide variety of dimensions studied and instruments used as well as a number of methodological weaknesses, including small sample sizes, short-term assessments, and failure to account for missing data. Conclusion: A standardized approach to the assessment of HRQL in hypertensive patients is needed so that research in this area can be of value to clinical practice and to hypertensive patients and their families.
